hassio "sendBatteryLevel" value not on user interface

[peerv]

Installed latest version of hassio on a Pi with a serial gateway attached.
send(voltMsg.set(Vbat, 1)) is working fine and the value appears on the HA UI.

sendBatteryLevel with battery percent of 93 is not appearing on the HA UI.
Sketch console log shows correct battery level of "93" send.

HA persistance file entry for the node also shows "battery_level": 93
Protocol version is 2.1.1

Any ideas why battery level is not showing up on the HA console?
Do I need to put some node entry in the config file?
